Document Summary
Sun is most likely to engulf the earth during asymptotic giant branch (it"s the largest phase) Creates a type ia supernova when mass exceeds the chandresekhar mass (and explodes) Show no hydrogen in their spectrum, but with silicon lines present. Unlike other kinds of supernova they do not occur when the core of a star collapses, but when a white dwarf exceeds the chandrasekhar mass. Neutrons in a neutron star are formed when electrons are forced under intense pressure to combine with protons. A black hole, white dwarf and neutron star, all of which have the same mass as the sun. Smallest to largest: black hole, neutron star, white dwarf. 99% of the energy from a supernova escapes in neutrinos. Population ii stars are older and have less metal. Population i stars are younger w more metal. Which of the following does not involve nuclear fusion: classical nova, x-ray burst, pulsar, type ia supernova.
